Q

Isotonic Solution

A

Two solutions having the same osmotic pressure across a semipermeable membrane. This state allows for the free movement of water across the membrane without changing the concentration of solutes on either side

2
Q

Hypertonic Solution

A

The concentration of solutes is greater outside the cell than inside it. Fluid will leave the cell and go into interstitial space

3
Q

Hypotonic Solution

A

The concentration of solutes is greater inside the cell than outside of it

4
Q

Tonicity

A

Cells affected by the osmolality of fluid around them

5
Q

Osmolality

A

Total solute concentration in an aqueous solution

6
Q

Permeability

A

Cells that are selectively permeable

7
Q

Selectively Oermeable

A

Permits free passage of some material and restricts others

8
Q

Intracellular Fluid

A

Fluid inside of cells (67%)

9
Q

Extracellular Fluid

A

Fluid outside of cells (32%)

10
Q

Intravascular Fluid

A

Is part of extracellular fluid; fluid in blood vessels (8%)

11
Q

Interstitial Fluid

A

Is part of extracellular fluid; fluid between the cells and blood vessels (24%)

12
Q

Inflitration

A

IV fluid enters the surrounding space around venipuncture site

13
Q

Phlebitis

A

Inflammation of the vein

14
Q

Fluid Volume Excess

A

Patient receives too much fluid

15
Q

Coronary Atherosclerosis

A

A buildup of plaque inside the artery walls. This buildup causes the inside of the arteries to become narrower and slows down the flow of blood.

16
Q

Cardiovascular Disease

A

A class of diseases that involve the heart or blood vessels

17
Q

Peripheral Vascular Disease (PVD)

A

Is a blood circulation disorder that causes the blood vessels outside of your heart and brain to narrow, block, or spasm. This can happen in your arteries or veins. PVD typically causes pain and fatigue, often in your legs, and especially during exercise

18
Q

Vasodilation

A

Is the widening of blood vessels. It results from relaxation of smooth muscle cells within the vessel walls, in particular in the large veins, large arteries, and smaller arterioles. When blood vessels dilate, the flow of blood is increased due to a decrease in vascular resistance. Therefore, dilation of arterial blood vessels decreases blood pressure.
